"Forensics" Phadebas test

A Phadebas test is a very accurate method of testing when conducting an investigation where suspicion of cunnilingus is involved. This is because; the Phadebas Forensic Press test is used for detecting and identifying hidden saliva stains. Locating saliva stains is a challenging task to perform. This is why; the area of choice I would determine would be the inside of the panties.  In addition, to the Phadebas testing I would also use light sources. Even though, saliva stains can not always be seen using light sources if something was to show, I would have a better idea where to use the Press test. Furthermore, it is always good to conduct other of methods of testing, especially in a complex case. As a matter of fact, a study has shown that as many as 40% of saliva stains on garments go undetected (Wikipedia). Phadebas is a great method of testing in a case like this. Because, Phadebas testing  is capable of locating saliva on any item or surface. Allegedly, Phadebas Forensic Press test is selective, the reason being that alpha-amylase activity in saliva is typically several orders of magnitude higher than in other body fluids. The methodology isn't new, as this has been implemented in many forensic labs world wide for many years. The earliest use of the Phadebas test was first used in 1970 ( Wikipedia).
